AIR-MOISTENING- VENTILATOR.

Specification of Letters Patent. i

Patented May 16, v191e.

Application filed. May 14, 1915. Serial No. 28,128.

To all whom t may concern Be it known that I, `WILLIAM H. LESH, a citizen ofthe United States, residingv at Delphi, in the county of Carroll and State of Indiana, have invented certain new and useful Improvements in VJAir-Moistening Ventilators, of which the following is a4 specification.

My invention relates to ventilators, and

more particularly to a new and improved grating having an air inoistening device associated therewith. Y

The primary object of my invention is to provide a ventilator of the class above described which is simple in construction, cheap to manufacture, strong and durable and effective in operation.`

Another object of my invention is to provide improved meansfor retaining the ventilator grating in position, and means for supporting a liquid containing tank on the grating. Y

With the above and Vother objects in view my invention resides preferably in the construction, combination, and arrangementof parts as hereinafter set forth in the specication and illustrated in the accompanying drawings, in which- Figure 1 is a top plan view of my invention showingthe same seated in an opening such as isrprovided for Ventilating purposes.

Fig, 2 is a longitudinal sectional view' taken on the line 2 2 of Fig. 1 and looking in the direction of the arrow.

Similar reference characters indicate similar parts throughout the various views of the drawings.

Referring more particularly to the drawings in which the preferred embodiment of my invention is illustrated, the lioor of a dwelling or the like is designated 1, said floor having a substantially `rectangular opening 2 therein and transverse strength ening beams 3 adjacent said opening for a purpose which will hereinafterv appear.

Myinvention includes a grating member Y Y comprising a plate .4 having a plurality of elongated apertures 5 therein, such as is common in ventilators, said plate having a downwardly extending tapered flange'k 6 formed integral therewith. A laterally extending iange 7 is providedon the plate 4k and is receivable in the countersunk portion 8 formed adjacent the opening 2 in the floor 1. The flange 7 is provided with a plurality of apertures through which screws 9 or simiregister.

lar fastening means are inserted to perinanently secure the ventilator structure in the opening 2, The plate 4 is provided with a relatively large rectangularopening 10 pref-y able in the 'opening 10. The upper mar-1 ginal edges of the walls 15 of the tank 14 are provided with laterally extending flanges 16 which are adapted to seat on the flange 11, as shown to advantage in Fig. 2. When vthe tank 14 is dropped into the opening 10 and seated on the flange 11 the cover 12 may be Vclosed,'this serving both to protect the tank 14 and to allow persons to walk upon the ventilator. kIt also retains the tank in the position shown 'in Fig. 2. It will be noted that the flanges 6 formed on the plate 4 are receivable in the opening 2 and serve to yprevent lateral displacement of the ventilator. The tank has been broken awayin Fig. 2, as shown at 13', in order to illustrate to advantage one of the hinges 13. Y.

Particular vattention is called to the peculiar manner of securing the tank l in position, as wellas the manner in which the opening 10 is disposed in the plate 4, and the provision of the flanges 6.

It is desired that it be understood that the ventilator structure shown need not be placed in the licor of a dwellingbut may be placed in the walls thereof, it'being, of course, necessary to provide a deliecting channel or air conveying duct extendingAV from the wall which will support the ventilatorl in a horizontalv plane. The peculiar structure allows of quick removal of .the

tank for .cleaning and replenishing ofthe liquid and in cold weatherl the tank may be removed and the ventilator used asa heat Of course, it will be understood that when using the same as a heat register,

the tank may be left in position and the same filled with liquid to meisten the warm air passing therearound.

While I have shown and described 1ny invention as possessing a peculiar form and construction, it is desired that it be understood that I may make such changes in the details thereof that do not depart from the spirit and scope of the invention as claimed. Having thus described my invention,wh'at I claim and desire to secure by Letters Patent is:

l. A ventilator and air moistener, including a perforate plate having' a relatively large central opening, a supporting flange adjacent the opening and a liquid receptacle receivable on the iange and Within the opening.

2. A ventilator and air inoistener, including a perforate plate having a relatively large central opening, a liquid receptacle supported in the opening, and a perforate cover over the opening for protection of the receptacle and retention in position of the latter.

3. A ventilator and air moistener, including' a perforate plate having a relatively large central opening and a downwardly directed tapered flange, asupporting iange adjacent said central opening, a perforate opening and adapted to seat on the supportf ing iianges, said cover being` adapted to proltect thereceptacle and retain the saine in position.

t. A ventilator' and air inoistener, including a perforate plate having a rdownwardly extending tapered iange, said plate having a relatively large central opening, a perforate cover for the opening, a tank, a supporting flange on theplate adjacent the relatively large opening, and lateral iianges on the upper marginal edges of the walls of the tank receivable between said supporting flanges and the hinged cover, whereby to retain the tank in position and allow the cover to lielush with the upper face of the plate. 'f

In testimony whereof I athx my signature in presence of two witnesses. c
